Use of a window glass comprising a profiled bead for installing it in an opening

ABSTRACT

A window glass, particularly for installation by adhesive bonding in an opening of a vehicle bodywork, comprises a sheet of glass with a profiled bead that is fixed at least to the main surface of the sheet of glass facing toward the interior in the installed state and that rests against at least part of the opening. The use of such a window glass makes it possible, once the window glass has been installed in the bodywork opening, to obtain a visible space less than 5 mm between the opening and the edge face of the window glass.

CROSS-REFERENCE TO RELATED APPLICATIONS

[0001] This application is a continuation of the U.S. National Stagedesignation of co-pending International Patent ApplicationPCT/FR00/02818, filed Oct. 10, 2000, the entire contents of which areexpressly incorporated herein by reference thereto.

FIELD OF THE INVENTION

[0002] The invention relates to the field of window glass, particularlyfor motor vehicles, and is aimed more specifically at window glassesequipped with decorative and/or functional elements attached to theglass. More particularly, the invention relates to a window glass,particularly for installation in an opening in vehicle bodywork,comprising a sheet of glass with a profiled bead that is fixed at leastto the main surface of the sheet of glass facing toward the interior inthe installed state. This bead may, by way of covering appendage,comprise a lip projecting beyond the edge of the window glass with asealing rib which can be applied against an adjacent wall part when thewindow glass is being installed.

BACKGROUND OF THE INVENTION

[0003] It is a generally known practice for vehicle window glass to bebonded into the respective openings in the vehicle bodywork. To thisend, window glasses are often provided with a profiled bead that adheresat least to the main surface of the glass facing toward the interior, inthe installed state. A run of adhesive is applied to the profiled beadand/or near to the profiled bead on this same main surface of the glass.The window glass provided with the run of adhesive is then inserted intothe opening in the vehicle bodywork. The latter is surrounded by amounting flange, to which the run of adhesive is applied. Window glassesin the installed state preferably lie practically flush with theexternal surface of the bodywork. For such installation, the mountingflange is recessed with respect to the main surface of the bodywork bymeans of a peripheral angled step. The height of the angled stepcorresponds to the thickness of the window glass and of the adhesive. Incertain embodiments, the edge faces of the window glass are not coveredby the profiled bead. As the dimensions of the window glass and theperiphery of the opening cannot be matched to one another withouttolerance, due to of dimensional variations in manufacture, a spaceremains, in the form of a groove, between the angled step or the edge ofthe opening and the window glass.

[0004] According to document DE-A1-38 18 930, there is provided, forcovering this space, a lip formed directly on the profiled bead bondedto the window, for example by extrusion. In another alternativeembodiment from the same document, an additional profiled strip made ofa flexible elastomeric plastic is bonded along the peripheral surface ofthe window on the main surface that faces toward the interior. Thisprofiled strip has a tubular portion, which fills said space when thewindow glass is in the mounted state.

[0005] A shape of profile is also known (from DE-A1-43 01 026), which onthree sides surrounds the external edge and the edge face of the windowin one embodiment, that is to say also on the external main surface, andwhich further comprises a lip projecting from the window glass andserving to cover the lateral slot.

[0006] Thermoplastics, preferably thermoplastic elastomers (TPE) orthermoplastic olefins (TPO) have mainly been used hitherto as materialsfor such profiles. With these materials, the lip can be manufactured sothat it is already thin enough at the extrusion stage, so that it can beflexed elastically against the edge of the opening when the window glassis installed in the bodywork without generating excessively highreactive forces during the mounting. In addition to its sealingfunction, the lip centers the window glass in the opening duringinsertion and keeps the window glass centered.

[0007] Dirt can still build up in the space thus covered by thefolded-over lip disclosed in the prior art, and can be removed from thebottom of the groove only with difficulty. The space that remains ingeneral actually is greater than 7 millimeters and thus allows a greatdeal of dirt to accumulate.

[0008] The present invention relates to a new type of mounting for awindow glass comprising a profiled bead that avoids the aforementioneddrawbacks and does not require a finishing strip to cover part of thewindow glass.

SUMMARY OF THE INVENTION

[0009] The invention relates to a window glass that is designed inparticular to be installed by adhesive bonding in an opening of a motorvehicle bodywork, comprising a sheet of glass with a profiled bead thatis fixed at least to the main surface of the sheet of glass facingtoward the interior in the installed state and that rests against atleast half of the opening. After installation, the visible space betweenthe opening and the edge face of the window glass is less than 5millimeters and preferably less than 3 millimeters.

[0010] The “edge face of the window glass” is to be understood asmeaning either the edge face of the window itself or, if the profiledbead covers it, the corresponding portion of the bead. The profiled beadaccording to the invention may be a continuous or discontinuous elementand may be a single or multiple element, that is to say may consist ofat least two practically parallel parts deposited at the periphery ofthe sheet of glass.

[0011] The invention thus makes it possible to obtain closure flush withthe main surface of the window and with the adjacent wall or bodyworksurface. In addition to the technical advantages afforded, this thenvisually yields a practically closed surface. The technical advantagesare essentially the fact that the visible space between the bodyworkopening and the window glass is reduced and that the risk of said regionbecoming soiled is avoided.

[0012] The invention results fro a choice by the inventors not to followthe typical design precautions; instead, the inventors chose to reducethe space between the window glass and the opening by demonstrating,contrary to that which might be expected by a person skilled in the art,that the technique according to the invention was acceptable and did notrun the risk of damaging the window glass.

[0013] According to an advantageous embodiment of the invention, theprofile is designed to limit the expansion of a bead of adhesive, and inparticular the lateral expansion thereof. The shape of the profiled beadthus advantageously is designed to prevent the adhesive used to fix thewindow glass into the bodywork opening from excessively spreading anddisrupting the field of view of the window glass. This shape alsoadvantageously makes it possible to define the spacing between thewindow glass and the bottom of the bodywork opening and therefore allowpredetermined positioning in at least one direction. The shape of thebead thus defined also makes it possible to predetermine the amount ofadhesive needed to fix the window glass and thus permit the window glassto be firmly secured while making it easier for operations to beautomated.

[0014] According to a first embodiment of the invention, a bead ofadhesive at least partially covers the profiled bead. In particular,depending on the nature of the profiled bead and on the nature of thebead of adhesive, the securing of the window glass is reinforced by thebinding of said two beads. The bead of adhesive may be wholly depositedon the profiled bead and their binding thus may be directly associatedwith the securing of the window glass. Advantageously, in order to bindthe two beads, the forces of bonding and the forces of mechanicalattachment may be combined. To this end, the profiled bead preferably isprovided with anchoring projections. These projections accommodate thebead of adhesive which, after curing, is mechanically held.Advantageously, the invention also relates to an alternate embodiment inwhich no adhesion occurs between the two beads; such an embodiment mayfacilitate removal of the window glass, if necessary. Indeed, if themechanical binding between the two beads is of the nesting type, thewindow glass may be readily removed.

[0015] In other cases, where the bead of adhesive at least partiallycovers the profiled bead and, in particular, when the sheet of glasscomprises at least two sides which have curvatures with small radii ofcurvature, the profiled bead is produced with a slope such that itssurface is inclined downward from its edge oriented toward the center ofthe window glass toward its other edge positioned at the edge of thesheet of glass. Such an embodiment applies more particularly towindshields or back lights, the lateral approach angles of which aresmall. In this embodiment, the bead of adhesive subsequently may bedeposited by robot with ease; the slope of the profiled bead withrespect to the plane of the window glass in this region allows the planeof depositing of the bead of adhesive to be straightened up in thedirection of the horizontal when the window glass is resting on itscenter of the convex side.

[0016] According to another alternate embodiment of the invention, thebead of adhesive does not in any way cover the profiled bead. The onlycontact between the two beads is possibly related to the fact that theprofiled bead may be designed to limit the lateral expansion of the beadof adhesive.

[0017] According to a preferred embodiment of the invention, theprofiled bead has, over at least part of its length, a lip that projectsbeyond the edge of the window glass. Such a lip advantageously is madeto be deformable or flexible. These features give the lip mechanicalproperties that allow said lip to perform various functions. First, whenthe lip is over all or part of at least two sides of the window glass,it will act as a centering tool for positioning the window glasscorrectly in the bodywork opening. Also, for example, when a lip isprovided on the upper part of the window glass along all or part of thelength of the profile and when the bottom of the window glass rests onstops, said lip may supply a reactive force against the bodywork openingfacing it, thus providing a defined space between the bodywork openingand the window glass. Furthermore, the lip avoids any risk of contactbetween the sheet of glass and the bodywork and therefore any risk ofdamaging the sheet of glass.

[0018] The lip thus produced also may have a sealing function betweenthe opening and the window glass; the lip will bend in one direction orthe other, as chosen, and will press against the opening. The pressurethus exerted is enough to provide a good seal. For this function, thelip advantageously is provided along at least three sides of the windowglass; it is not actually essential for the lip to be present on thebottom part of the window glass when the latter is installed.

[0019] According to an advantageous embodiment of the invention,provision is made for a solid wire to be incorporated into the bead ofadhesive or into the profiled bead. The purpose of such a wire is tomake it easier to remove the window glass, if necessary, and inparticular, to allow materials to be recycled.

[0020] Such a bead is inserted for example into or under the bead ofadhesive when the latter is produced, taking care to let at least oneend of the wire protrude. It thus may be possible when the window glassis in place to grasp hold of this end, possibly using a tool, and then,by pulling on the wire possibly also using a tool, to break the bead ofadhesive.

[0021] Such a device making it possible to break the bead of adhesive orthe profiled bead is practically essential in the context of theinvention if the window glass is to be removed. The space visiblebetween the window glass and the bodywork opening, which space issmaller than 5 millimeters, does not permit access by a cutting tooland, in any case, would not allow such a tool to be operated. Indeed,only the case mentioned previously whereby the binding between thewindow glass and the bodywork is of purely mechanical nature when theprofiled bead has anchoring projections permits the window glass to beremoved without providing a device such as a cutting wire. However, thepresent invention also contemplates the combination of such a wire withthis mounting exhibiting only mechanical retaining means; in such acase, the wire is no longer truly a cutting wire but provides assistancewith disengaging the bead of adhesive and the profiled bead.

[0022] According to another advantageous embodiment of the invention, atleast two wires are incorporated into the bead of adhesive or theprofiled bead. The wires are preferably positioned some distance fromone another so that each wire need only slit through part of the bead ofadhesive. The forces needed for this operation are therefore reduced.

[0023] Means in particular for fitting such wires are, for example,described in patent applications EP-A-0 121 480 and EP-A-0 298 788.

[0024] Still according to this same principle of incorporating anelement into the bead of adhesive or into the profiled bead, oralternatively at least incorporating an element between the profiledbead and the bead of adhesive, the invention advantageously relates tofitting a sheath into which another element can then be inserted. Thismay then be a cutting wire or alternatively another type of elementhaving a different function.

[0025] In one advantageous embodiment of the invention, a profiled beadis made of a two-part material. For example, the profiled bead may beformed of a polyurethane. The choice of such a material has theadvantage of providing excellent compatibility with the intendedadhesive, it easily being possible for this adhesive to be chosen from asimilar kind.

[0026] In another embodiment of the invention, the profiled bead isproduced from a thermoplastic. Such material in particular has theadvantage of being easy to recycle, which is often a requirement. Asregards the compatibility of a thermoplastic with the adhesive, suchcompatibility is not always easy to obtain. When necessary, particularlywhen the bead of adhesive at least partially covers a profiled bead madeof a thermoplastic, the surface of the latter advantageously may becoated beforehand with an adhesion primer.

[0027] In both instances, the means of producing the profiled bead arevaried.

[0028] According one embodiment, the invention advantageously provides aprofiled bead directly obtained by extrusion onto the surface of thesheet of glass. Advantageously in the case of a profile made of athermoplastic, the extrusion device and, in particular, the extrusionhead and piping may be heated.

[0029] Alternatively, the profiled bead and the bead of adhesive may becoextruded directly onto the sheet of glass. The bead of adhesive mayremain plastically deformable and adhesive until the window glass isfitted into the bodywork opening.

[0030] According to another embodiment of the invention, the profiledbead is manufactured beforehand, for example by extrusion, and laterfixed to the sheet of glass, for example by adhesive bonding. Such aprofile, for example, is made by extrusion in a long length and then cutto the required length for a given window glass and fixed thereto. Tofix the profiled bead, it is possible to adhesively bond it, for exampleby providing a perforated profile with the adhesive being able to passthrough the holes, come into contact with the sheet of glass, and thussecure the profile firmly.

[0031] According to another embodiment of the invention, the profile isobtained using an encapsulation technique.

[0032] According to any of these techniques of obtaining the profiledbead, said profiled bead is produced on the internal face of the windowglass, when the latter is fixed into the bodywork opening. However, theprofiled bead may still cover part of the edge face of the glass windowand/or cover part of the external face of the window glass.

[0033] The profiled bead and/or the bead of adhesive may be in directcontact with the glass or in contact with an opaque layer, such as anenameled coating, itself deposited onto the glass.

[0034] As regards the window glass, this consists of at least one sheetof glass and may therefore consist of a laminated window glass.

[0035] The invention also provides a window glass consisting inparticular of a sheet of glass comprising a profiled bead and inparticular intended to be fixed by adhesive bonding into a bodyworkopening and which, in particular, can allow use as described previouslyand for example be fixed in such a way that the space visible aftermounting between the window glass and the bodywork opening is less than5 millimeters.

[0036] Other advantageous details and features of the invention will bebecome apparent hereinafter from the exemplary embodiments of theinvention with reference to FIGS. 1 to 3.

BRIEF DESCRIPTION OF THE DRAWINGS

[0037] Preferred features of the present invention are disclosed in theaccompanying drawings, wherein similar reference characters denotesimilar elements throughout the several views, and wherein:

[0038]FIG. 1 shows a partial cross-sectional perspective view of a firstembodiment of the invention;

[0039]FIG. 2 shows a partial cross-sectional perspective view of asecond embodiment of the invention; and

[0040]FIG. 3 shows a cross-sectional side view of an embodiment of theinvention using another window glass.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

[0041]FIG. 1 depicts a window glass consisting of a sheet of glass 1provided with a profiled bead 2 adhering near its edge to one of itsmain surfaces, which will be the interior surface once the window glasshas been installed in a bodywork opening.

[0042] The profiled bead 2 can be deposited directly onto the surface ofthe sheet of glass 1 or, as illustrated here, onto a coating 3, such asan enameled layer deposited by screen printing. The profiled bead 2 isdeposited preferably by extrusion or by some other method such asovermolding or encapsulation, adhesive bonding of a prefabricated bead,etc. It is made of a thermoplastic, preferably an elastomer or a blendof thermoplastic elastomers (TPE) or thermoplastic olefin(s) (TPO(s)).It may also be a two-part material such as a polyurethane.

[0043] The sheet of glass 1 may consist of glass or a transparentplastic and may be produced monolithically or, unlike the illustration,with a laminated structure combining at least two sheets of glass and/ortransparent plastic.

[0044] Profiled bead 2 essentially comprises a base profile resting on amain surface of the sheet of glass. This profile projects practically atright angles from the surface of the sheet of glass 1 and, at its freeend, forms a bearing rib 4. The latter, in the installed position, isdisposed against a mounting flange of a bodywork opening and will, uponmounting, define the position of the window glass in the bodyworkopening in terms of the depth to which it is set in said opening.

[0045] In the embodiment depicted, profiled bead 2 adheres only to themain surface of the sheet of glass 1 intended to face toward theinterior. As an alternative, profiled bead 2 may cover two or threefaces of the sheet of glass, namely a main surface and at least part ofthe edge face of said sheet of glass or, respectively, the two mainsurfaces and the edge face of the sheet of glass, straddling the edge ofthe latter.

[0046]FIG. 2 illustrates another type of window glass consisting, asbefore, of a sheet of glass 5 but, as already stated, could be a sheetof plastic or a laminated window glass. A profiled bead 6 producedaccording to one of the previously mentioned methods and materials isfixed to the sheet of glass 5 or, more precisely, to an opaque layer 7,itself deposited on at the periphery of the sheet of glass 5.

[0047]FIG. 2 also depicts a bead of adhesive 8 deposited on profile 6.This bead of adhesive 8, in some embodiments, may be deposited directlyon the sheet of glass 5 or the opaque layer 7, or alternatively maypartially cover profiled bead 6. The bead of adhesive 8 is depositedbetween two bearing ribs 9 which will limit the expansion of theadhesive on each side, and define the distance separating the bottom ofthe bodywork opening from the window glass.

[0048] The profiled bead 6 additionally comprises a lip 10 projectingbeyond the edge of the window glass.

[0049] The lip 10, formed of one piece, projects from base profile 6 ata certain angle with respect to the main extension of the latter,possibly practically parallel to the main surface of the sheet of glass,more or less mid-way between the sheet of glass 5 and the bearing ribs9, and extends beyond the periphery of the sheet of glass 5.

[0050] In this configuration, lip 10 may have different functions. Lip10 advantageously forms an elastically deformable part of profiled bead6. The lip 10 can thus be deformed upon installation in the bodyworkopening and act as a centering element. Of course, lip 10 also has afunction of protecting the sheet of glass 5 because it prevents anyaggresive contact between said sheet of glass and the metal parts of thebodywork opening. Furthermore, lip 10 also may have a sealing functionbecause it is applied under great pressure against the bodywork opening;its deformation, at the very least, may make it possible to formchannels for discharging rain or washing water. The functions of thislip will be further discussed in connection with the description of FIG.3.

[0051] Referring again to FIG. 2, a cutting wire 11 is shown to beincorporated into profile 6. Such a wire could even be fitted in thebead of adhesive 8 or between the two beads. At least one end of wire 11is left free so that, after mounting, it can be grasped by an operator,possibly using a tool. A tensile force may permit either the bead ofadhesive 8 or the profiled bead 6, as in the case of FIG. 2, to be cut.

[0052]FIG. 3 schematically illustrates an embodiment according to theinvention for mounting of a window glass 12 comprising a profiled bead13 in a bodywork opening 14, using a bead of adhesive 15. Also shown inaddition to a window glass 12 and a profiled bead 13 is the edge of anopening 14 in bodywork which is not further illustrated. Window glass 12is connected by adhesion to the bodywork upright 14 by means of a beadof adhesive 15 applied to the profiled bead 13. Lips 16 also are shownextending profiled bead 13 so as to project beyond the edge of thewindow glass 12 in their deformed state. FIG. 3 also clearly shows thevarious functions of said lip, particularly the centering, sealing andwater run-off functions.

[0053] In the mounted state, the external main surface of window glass12 is practically flush with the external surface of the bodywork.Furthermore, according to the invention, the space 17 visible betweenthe bodywork opening and the window glass has a size less than 5millimeters.

[0054] By comparison with the earlier configurations for the mounting ofsuch window glasses the present invention provides a space between thewindow glass and the bodywork opening making it possible to avoid thebuild-up of dirt. Furthermore, it has been found that a reduction insaid space also makes it possible to reduce aerodynamic noise. Anotheradvantage of the present invention is that it affords a very particularvisual and attractive appearance, because, to an observer standing arelatively short distance away from a vehicle with this set-up, thewindow glass appears to be an uninterrupted continuation of thebodywork.

[0055] The detailed description which has just been given relates moreparticularly to a window glass equipped by extrusion with a profiledbead which adheres to a main surface.
